I'm not asking which games which are part of a series do you own the most installments of, i.e. if you have every Final Fantasy game, but rather what single title(s) do you own the most versions of.
For example, I have Columns for the:
- Coleco Sonic 20-in-1 Handheld
- Game Gear
- Game Gear (Japanese version)
- Genesis
- PS2 (SEGA Classics Collection)
- PS2 (SEGA Genesis Collection)
- PSP (SEGA Genesis Collection)
- SEGA CD (SEGA Classics compilation disc)
- SEGA Master System
- XBOX360 (Sonic's Ultimate Genesis Collection)
I'm not sure if I have more versions of this game floating around, but I wouldn't be surprised at all. I also doubt that Columns is the game I have the most versions of. I just used it as the first example I could think of. I'll have to really think about what the most prolific title in my collection is. What about you guys?
